Mathematics: percentage change

• The % change is calculated as (new value - old value)/(old value) x 100%.
• % decrease = (-(new - old) / old) x 100
• % increase = ((new - old) / old) x 100
• Percentage increase = (increase / original) x 100
• % decrease = (-((New Value - Old Value) / Old Value)) * 100
